The biggest star of Calgary's first Nuit Blanche was also the one the burned the brightest.

A giant cloud composed of 6,000-plus lightbulbs was definitely the hit of the night. Aptly named "CLOUD", Caitlind Brown's installation was constructed mostly out of donated light bulbs, given to Brown when she launched a light bulb drive through Calgary last month.

Thousands of people spent time under the illuminated sculpture, pulling at the strings, turning the lights on and off and snapping photos.

According the Wikipedia the Nuit Blanche concept started with Jean Blaise, founder of the Research Center for Cultural Development in Nantes, France. Blaise created and promoted a series of smaller, all-night festivals around the world and when Bertrand Delanoe became mayor of Paris in 2001 Nuit Blanche was born. Nuit Blanche is now celebrated in more that 120 cities around the world.
